Additional Information

Performance Technology

Light conditions are constantly changing. To get the most out of Costa lenses, it's important to choose the right color. We offer seven lens colors that range from low-light like dawn to extremely bright light with blinding glare.

Innovative Sweat Management System*

Ventilation

New ventilation ducting allows airflow through the end piece of the frame, which helps to keep you cool, reduces lens fogging, and works in conjunction with the sweat management template channels.

Nose pad ventilation.

Sweat Management

Channels run the length of the temple that enable airflow from the vents to cool, wick away sweat and moisture, and drain through the openeings on the temple tips.

Thinned-out inner bottom eyewire tucks closely into the back surface of the lens, which allows sweat and moisture to drain down the back surface of the lens and off the bottom of the frame.

Textured Hydrolite® nose and temple pads help manage sweat and heat - and provide a secure fit and all-day comfort.

The features of our sunglasses influence the way the sunglasses fit, like the hinges and temple construction.
